and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a vertical section through line :0

of Fig.3. Fig. 2 is a central vertical section of the outer cylinder B and the inner cylinder D, the elbow of the smoke-stack being shown permanently attached to the outer cylinder, in such manner that the inner cylinder may be removed without interfering with it. Fig. 3 is a plan view, and Fig. 4 is a planview of the ash-pan.

Similar letters of reference indicate like parts. 7

This invention relates to that class of feedcookers which are adapted to be used in connection with an ordinary barrel or cask; and consists mainly, first, in the combination of an outer cylinder, having a stove-pipe elbow per- .manently attached thereto, with an inner cylinder and grate-section, adapted to be readily removed from the outer cylinder; and, second, in the peculiar construction of the ash-pan and the handles by which it is removed.

. Arepresents the barrel, and B the outer cylinder. The bottom of part B is closed, and all is water-tight. At the top is a cast-iron ring,

B to'which the cylinder B is securely riveted. This casting ends at one side in an elbow, b, to which the smoke-stack B is attached. It also contains the adjustable damper b whereby the draft can be regulated. A circular head, v(l, fits on the ring B, and has in its center the ventilator C.

The inner cylinder D is made of sheet metal, and is riveted to the head 0. Below is the vertical grate D and hanging to it is the basketgrate D This makes parts D, D, and D practically one piece, which can be removed in one operation. I

Below the grateis the ash-pan E, having to form two legs.

long rods 0 extending almost to the top, and terminating in eyes 6. These rods extend below the bottom of the ash-pan a short distance The other two legs intermediate consist of short pieces inserted in the bottom plate. This construction leaves a space at 0 wherein the heat circulates and transmits the heat to the bottom.

To the casting B is attached the two short tubes F F, which form handles for the manipulation of the structure. The pendants ff are provided with eyes below, which slip over nails f f, driven into the barrel.

The operation of my invention is as follows: The head 0 and grates 1) D which are attached to it, are all withdrawn and a fire kindled in the grate with any fuel that is most convenient. The entire parts can then be replaced in the position as seen in the drawing, and the damper adjusted to suit the draft. The air to support combustion enters the ventilator O and arrives at the fire through part D, while the smoke and gas escape through the space between parts D and B, finding its escape through cavity 1) and stack B Should more fuel be required during one operation, this can be supplied by raising the ventilator or damper O, which also serves to regulate the draft more accurately than the damper in the elbow, which is simply to be set as-a check against the excessive passage of heat to the smoke-stack.

When the boiling is complete the two pendants ff are slipped outward, thus disengaging them from the nails f f, when the entire structure can be removed, and afterward, also, the contents of the barrel.

The arms F F serve the purpose of convenient handles, whereby the operator can rotate the cooker in the barrel and push it down against the resistance of the feed.

It is of great importance to the proper work- 'ing of a feed-cooker that the firegrate and ash-pan can be removed and replaced at any time without disturbing the other parts.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
